animal cells

Cards (11)

  • Organisms are made up of cells
  • Most organisms are multicellular and have cells that are specialised to do a particular job
  • Microscopes are needed to study cells in detail
  • Animal cells
    Almost all animals and plants are made up of cells. Animal cells have a basic structure.
  • Cytoplasm
    A jelly-like material that contains dissolved nutrients and salts and structures called organelles. It is where many of the chemical reactions happen.
  • Nucleus
    Contains genetic material, including DNA, which controls the cell's activities.
  • Cell membrane
    Its structure is permeable to some substances but not to others. It therefore controls the movement of substances in and out of the cell.
  • Most cells are specialised and are adapted for their function
  • Animals and plants therefore consist of many different types of cell working together
  • mitochondria
    where most energy is released in respiration
  • ribosomes
    tiny structures where protein synthesis occurs
